Questions
Do I need to know how to code?
No. You copy and paste the prompts on this page into ChatGPT or Claude, and the AI does the building. When it asks you something, you answer in your own words.
What does it cost?
The quick version, the app pack and the step-by-step instructions are for members: you pay the membership price, not a price per app (see the plans). Building the full app uses your own ChatGPT or Claude subscription. Putting it online is often cheap or no cost at the start, and your AI tells you before anything costs money.
How long does it take?
The quick version: about two minutes. The real app: an afternoon for a first version you can use, longer if you want every feature.
Can I change it to fit my business?
Yes. Tell your AI what to change in plain words, like “add a column for the price” or “use our logo and colours”. Or have Nexibeo build and customise it for you.
More detailsHow the AI works, safeguards and what to build first
Reduce the number of rented subscriptions and manual handoffs while keeping one approved localized version per language. For marketing and media teams publishing video content across several language markets, convert licensed video, transcripts, target-language lists and brand voice rules into reviewer-approved dubbed video versions linked to source clips. The benefit is a testable hypothesis, measured through approved localized versions per production hour and corrections after language review; do not assume that AI output alone produces business value.
Confirm the buyer's problem and scope, collect licensed video, transcripts, target-language lists and brand voice rules, then follow this sequence: 1. Import video by file or pasted link. 2. Transcribe speech and generate synced subtitles. 3. Translate transcripts into selected target languages. 4. Detect and separate multiple speakers. 5. Generate natural AI voices per language. 6. Clone an approved speaker voice where permitted. 7. Preserve speaker accent and tone in dubbed audio. 8. Align dubbed audio with the video's visuals. Resolve uncertain cases with qualified reviewers, approve reviewer-approved dubbed video versions linked to source clips, and measure approved localized versions per production hour and corrections after language review against a documented baseline.
How the AI works
Use AI to interpret permitted inputs, suggest structured mappings and generate candidate outputs for the three stated task modules. Use deterministic code for arithmetic, schema validation, hard constraints and reproducible tests. Review source-linked explanations and uncertainty before accepting results. One approved voice set and target-language list; final language and brand checks remain editorial. A model suggestion is never a verified fact, professional decision or authorization to act.
Safeguards
Preserve speaker voice, source attribution, quotation accuracy and usage permissions. Speakers and brand owners approve substantive changes and publication scope. One approved voice set and target-language list; final language and brand checks remain editorial. Keep all consequential actions under authorized human control and do not fabricate missing inputs, permissions, professional judgments or market evidence.
What to build first
Pilot scope: One approved voice set and target-language list; final language and brand checks remain editorial. Implement one approved input format, a bounded representative case set and the first two task modules: import video by file or pasted link; transcribe speech and generate synced subtitles. Support the third module with operator review: translate transcripts into selected target languages. Include source references, corrections, basic organization access, approval states, export and value measurement. Use managed operator assistance for unresolved exceptions. The cost estimate covers this narrow prototype, not unrestricted multi-tenant scale, complex production integrations, specialist certification or physical operations.
What it can connect to
Buyer-owned video libraries, authorized transcripts and permitted brand assets. Cloud asset storage, video-file import/export and publishing destinations. Start with file exchange and validate destination specifications before promising direct publishing. Start with authorized file exchange. Validate current provider access, usage rights and schema behavior before promising a connector.
The screens in detail
Primary screens: Source video and language brief, Editable dubbing preview, Client proof and delivery. Use a thumbnail gallery for projects, a large central player with synced transcript and dubbed audio, and a right-hand panel for languages, speakers, brand terms and comments. Let users compare source and dubbed versions side by side. Display draft, changes requested and approved states. Provide a client preview link with comments anchored to the relevant timecode. Make the task-specific outcome reviewer-approved dubbed video versions linked to source clips visible beside its evidence, review state and value baseline.
